Values are mean±SD unless stated otherwise.
Definitions of simple and complex surgical course are given in the text.
↵* p Value becomes NS when corrected for age.
CMR, cardiac magnetic resonance; NYHA, New York Heart Association; NT-proBNP, N-terminal pro-brain natriuretic peptide; RVEDVI, right ventricular end-diastolic indexed volume; RVEF, right ventricular ejection fraction; RVESVI, right ventricular end-systolic indexed volume.
